Název v původním jazyce

Mesomorphic, electro-optic and structural properties of binary liquid crystalline mixtures with ferroelectric and antiferroelectric liquid crystalline behaviour

Popis výsledku v původním jazyce

Two new binary liquid crystalline mixtures composed from the chiral liquid crystalline materials with fluorinated non-chiral chain and without lateral substitution at the molecular core have been designed and investigated by polarisation optical microscopy, differential scanning calorimetry, broad-band dielectric spectroscopy, and X-ray techniques. Both mixtures possess the paraelectric orthogonal smectic A*, the tilted ferroelectric smectic C* and the antiferroelectric smectic CA* phases over a reasonably broad temperature range. The gained results reveal a considerable improvement of (i) the broadness of the mesophases temperature range of the ferroelectric and antiferroelectric phases (up to 130 K broad) and (ii) electro-optical properties, namely the spontaneous polarisation (up to 200 nC/cm2) and tilt angle (higher than 40o), with respect to that of the original pure compounds.
